You can use the following basic formula to compare three columns in Excel:

=IF(AND(B2=C2,C2=D2),"Equal","Not Equal")

This particular formula compares the values in cells **B2**, **C2**, and **D2**.

If all of the values are equal, the formula returns **Equal**. Otherwise, it returns **Not Equal**.

The following example shows how to use this formula in practice.

**Example: Compare Three Columns in Excel**

Suppose we have the following dataset that shows the highest scorer on various basketball teams during three different games:

We can type the following formula into cell **E2** to test if the three values in the first row are all equal:

=IF(AND(B2=C2,C2=D2),"Equal","Not Equal")

The following screenshot shows how to use this formula in practice:

The formula returns **Not Equal** since the three names in the first row don’t all match.

We can then drag this formula in cell **E2** down to the remaining cells in column E to test for matches in each row:

Notice that the formula only returns **Equal** for the rows where the cell values are equal across each of the three columns.

You can also apply conditional formatting to the rows where all three cell values are equal by highlighting the cell range **E2:E11**, then clicking on the **Conditional Formatting** button on the Home tab, then clicking **Highlight Cell Rules**, then clicking **Equal To**:

In the new window that appears, type **Equal** into the box and choose a fill color, then click **OK**:

The rows that have matching values across all three columns will now be filled with green:
